Corps of Engineers and the District of Columbia convinced the United States Congress that the Anacostia River should be dredged to create a more commercially viable channel that would enhance the local economy as well as provide land where factories or warehouses might be built. The material dredged from the river would be used to build up the flats and turn them into dry land, eliminating the public health dangers they caused. Most of the reclaimed mudflats were subsequently declared to be parkland and named Anacostia Water Park (now Anacostia Park) in 1919. The original dredging plan called for a channel wide on the Anacostia's west bank from the 11th Street Bridges to Massachusetts Avenue SE, narrowing to a wide channel from Massachusetts Avenue SE to the Maryland-District border line. In addition to this channel (which was meant to facilitate the passage of cargo ships) the McMillan Commission proposed building a dam across the Anacostia River at Massachusetts Avenue SE or at Benning Bridge to form a large lake for fishing and recreational boating. The Commission also proposed using dredged material to build islands within the lake. The Washington Post reported in July 1914 that Congress had approved the plan for a dam on the river at Massachusetts Avenue SE. By 1916, the Corps of Engineers was still planning a dam, with access to the deep lake behind it controlled by locks. The Corps also planned to create several large islands in the lake and planned to replace Benning Bridge with a drawbridge to accommodate the cargo traffic through the lake. The firm of Sanford and Brooks began the dredging in January 1903, at which time the Army Corps of Engineers began surveying the surrounding land to determine whether the federal government or private landowners had title to the marshes themselves. By 1920, the Corps of Engineers had dropped the dam idea and proposed creating a deep lake on one side of the Anacostia River by linking several of the mid-river islands it had built with dikes. That same year, Congress specifically prohibited the Corps from extending Anacostia Park beyond Benning Bridge, which forced the Corps to drop its plans for a drawbridge. Early development efforts By March 1926, the Corps had begun calling the lake it had created Kingman Lake, after the well-regarded former head of the Corps, Brigadier General Dan Christie Kingman. The name was formally proposed in
